Two massive objects have -500 J of gravitational potential energy stored between them. What does that mean?

a) This situation is impossible b) None are correct c) The objects have 500 J more energy than they would have infinitely far away from each other d) The objects must have a kinetic energy of 500 J each e) It would take 500 J of work to completely separate them
